About the technology

ContiSeal™ is a technology developed by Continental designed to seal a damaged tire tread. In case of penetration by foreign objects such as nails, there is no need for immediate roadside tire changes, and holes remain sealed even if the puncturing object becomes dislodged.

ContiSeal™ is a sticky, viscous sealant layer. It is applied to the inside of the tire in the tread area. ContiSeal™ seals 80% of all tire punctures and therefore reduces the risk of flat tires. ContiSeal™ tires are marked clearly with a symbol on the sidewall and are compatible with all commonly available rims.

Technical instructions:

For optimal conditions, a Tire Pressure Monitoring System (TPMS) is recommended.

It is not necessary to stop immediately for a tire change. Your journey can be continued.

Upon discovering a puncture, a tire specialist must promptly check the tire.

Technical details

A ContiSeal™ tire contains a sticky, viscous sealant layer that covers the inside of the tire tread. It provides an almost instantaneous seal around any penetrating object (up to 5 mm in diameter in the tread area), trapping the air inside and keeping the tire inflated and your car mobile.

When a puncture occurs on a standard tire, the sidewall can get crushed between the rim and the road, leading to a potentially dangerous situation such as a blowout or the tire slipping off the rim.
